SURFACE CATTLE-GUARD.

SPECIFICATION forming part of Letters Patent No. 448,804, dated March 24, 1891.

I Application filed October 10, 1890. Serial No. 367,745. (No model.)

To aZZ whom it may concern.-

Be it known that I, JACOB K. WAGNER, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Surface Cattle-Guard, of which the following is a specification.

This invention relates to surface cattleguards which consist of sections composed of longitudinal bars parallel with the rails of the track and attached to transverse bars mounted upon the ties; and it has for its object the below described and claimed peculiar construction of longitudinal bars and cross bars and the mode of attaching them together.

In the drawings forming a part of this specification, Figure 1 is a plan view: Fig. 2 is a sectional elevation on a line near one of the longitudinal bars in Fig. 1. Fig. 3 is a section on line 6 G in Fig. 2, enlarged, looking from a point at the right; and Fig. 4 shows enlarged lettered details in perspective.

Referring to the lettered parts of the drawings, one of the sections is shown in Fig. l composed of theinverted-V-shaped transverse bars 13 and the inverted-V-shaped longitudinal bars I. The bars 13 rest upon the ties A of the track and are spiked thereto. Both sides of the longitudinal bars 25 taper toward their base, so as to be thinnest at the lower edge, as shown in Figs. 3 and at. I

At the apex the transverse bars B are provided with transverse slots 1, corresponding in shape to the shape of the longitudinal bars t, so that the latter bars can be inserted through said slots, as clearly shown in Figs. 1, 2, and 4. Thus the longitudinal bars are held from vertical and lateral displacement, and they are held from endwise displacement by rivets or bolts i, which pass down through the points of the bars I3, which are above or at the apex of the slots 0", and down through.

the slanting sides of the longitudinal bars I, as more particularly shown in Fig. 3. end of the longitudinal bars is turned down upon a curve to a point below the upper surface of the tiesA in the ordinary manner, as in Figs. 2 and 4, so that nothing will catch against said ends.

Each

\Vhileit is not absolutely necessary that the sides of the longitudinal bars shall be tapered as here shown, it is preferable that they shall be thus made, for the reason that the strength of the sides corresponds with the strength of the apex of said bars, and thereby secures a uniform strength throughout said bar with the least possible expenditure of metal.

It will be observed that in Fig. 1 only one section of the cattle-guard is shown, thedesign being to employ two sections between the rails of the traclgif desirable, and one section outside of each of said rails.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a surface cattle-guard, sections composed of longitudinal bars in the form of an inverted V in cross-section, transverse bars having transverse slots corresponding to the shape of said longitudinal bars, and the rivets or bolts attaching the projections above the apexof the slots to the longitudinal bars, substantially as set forth.

' 2. In a surface cattle-guard, sections composed of longitudinal bars in the form of an inverted V in cross-section and having their sides tapered from the apex to the base, and transverse bars having transverse slots corresponding to the shape of said longitudinal bars, and the rivets or bolts attaching the projection above the apex of the slots to the longitudinal bars, substantially as set forth.

3. In a surface cattle-guard, sections composed of longitudinal bars in the form of an inverted V in cross-section and having their sides tapered from the apex to the base, and transverse bars having transverse slot-s corresponding to the shape of said longitudinal bars, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.

JACOB K. \VAGNER.
